Pulse Width Modulation (PWM)


Reduced dBA with PWM speed control. Maximize efficiency with lower energy consumption.

Teflon Nano Bearings (TNB)


Self-lubricating TNB are quieter than other fans because of exceptional resistance to high temperature, vibration, and abrasion (MTBF 200,000 hours)

IP56 (Ingress Protection Rating)


High-level dust and water protected,
resulting in an extended lifetime.

Advanced 11-Blade Design


Advanced 11-blade design enhances the high airflow while reducing noise.
